To aZZ whom z' may concern Be it known that LCHARLns D. Bowrmz, a citizen of the United States, residing at:

' Camden, in the countyof Camden and Statef of New Jersey, have invented certain new and useful Improvements in Bottle-Closures..

of which the following is a specification.

My invention relates to improvements in bott-le closures, the object of the invention being to provide improved elastic means which will elastically connect a stopper .to the neck of a bottle or similar article, which willfpermit the stopper or closure to be moved to a position'to pour out the content-s of the bottle, and which will elastically. hold the stopper inclosed position and center the same against the end of the bottle neck. Y

A further object is to provide a bottle closure of the character above described composed of a plurality of coiled 'springspthe convolutions of the several springs interlocked, whereby they are-held in proper for-l mation relative to each other'and connected in 'an improved manner with a stopper or cover so as to eii'ectually hold the latter in closed position, yet allow it to be moved=to open position whenever desired.

A further object is to provideimprovements of the character stated which are adapted for use in'connection with any ordinary bottle neck-or receptacle having aV relativeiy small outlet such as used to hold condiments, and which may be manufactured and sold at a reasonably low price.

v With these and other objects in view, the invention consists incertain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims.

In .the accompanying drawings .2 Figure ll is a view in side elevation illustrating my improvements in connection withI one' form of bottle neck.l Fig. '2 illust-rates infnll lines, a side elevation at right angles to Fi-g. 1, and in dotted lines illustrates the cover in open position. Fig. 43 is a fragmentary view in section on the line 3 3 of Fig. l. Fig. l is a view in longitudinal section partly in elevation illustrating the constrnctionshown in Figs. 1, 2. and 3, and Fig.'` 5 is a view partly in section and partly in elevation illustrating a modification.

l represents acbottle neck having an'enlargeSl outlet'end'l 2. My improved closure comprises a "cap 3 having a flange 4- at its lower end and adapted to contain a co'ror' other block 5 which fits against the end of' the bottle neck andA acts as acomplete 'stopper or closure for the same when the capis 1n position. To hold the cap and stopperin operative relationship to the bottle neelg' I employ four coiled'springs 6, 7 8, Aand 9, re-

spectively. Thev springs 6, and 7, are located'inparallelism with 'the' ends of each spring 6 and connected by 'a coupling 10. Each coupling 10 is composed of a lstrip'oJE sheet metal having its ends bent in circular formation constituting eyes 11.

In assembling the parts, one spring vis screwed or turned with`itsv wire in one -of the eyes 11 until the end of the spring is'moved the entire length of the coupling. The other end of the spring is then positioned in the eye ll at the other end of the coupling, and

the spring turned or screwed in the reverse direction, so' that the ends of the spring will be together at a point centrally between the y ends of the coupling as indicated in Fig. 3. yIn constructing the device, the two springs 6 and 7 are firstl secured in circular formation by means of'their couplings, and then the` side springs S and 9 are connected to the -springs 6 and 7. It will be noted that the springs 8 and 9 are connected tothe springs 6 and 7- by intertwining or interlacing the convolutions of the springs. In other words, the wires forming the springs 8 and 9 are positioned around several convolutions of the spring 6, and then the springs 8 and 9 are turned so that they will be moved longitudinally, vet rem-ain firmly coupled to vthe spring 6, and when moved an Vappreciable distance with relation vto the spring 6. their ends are intertwined or coupled withthe convolutions of the spring 7, and the springs 8 and 9 turned until there is an effectual coupling or interlacing as indicated most clearly in Fig. 4. The four springs will thus be coupled together without. employing any third part. but relying solely uponthe intertwining or inter-lacing. of tlie-com'fo'lutions of the springs. The upper ends of the springs 8 and 9 are projected through Vopenings 1Q in the cap 3. and are hid from view. Furthermore. thev perform the useful function of limiting the movementof the block. or plug 5 in the cap.

As the springs S and 9 are located at diainetricallv opposite sides of the bottle neck. they will clasticallv center the stopper on the end of the bottle neck as seen inthe drawilo
